- 1Error HandlingChecking for errors is important since computers aren't able to check that text is correct; they can only recognize whether a word is in their built-in dictionary or not.
- 2Parity CheckingParity checking is one method used to check whether data had been changed or corrupted following transmission from one device or medium to another device or medium.
- 3Automatic Repeat Request (ARQ)ARQ is another method used to check whether data has been correctly transmitted.
It uses an acknowledgement (a message sent by the receiver indicating that data has been received correctly) and timeout (This is the time allowed to elapse before and acknowledgement is received) - 4CheckSumCheckSum is another way to check if data has been changed or corrupted following data transmission.
Data sent in blocks and additional value, the CheckSum, is also sent at the end of the block of data.
